Pneumatic tool

Abstract

A pneumatic tool includes a main body, a power mechanism, a slave valve, a master control lever and a connecting element. The main body includes a front housing and a back housing. The front housing includes a first accommodating space and is connected with the back housing. The power mechanism is disposed in the first accommodating space. The slave valve is coaxially connected with the power mechanism. The master control lever is disposed at the back housing and includes a first protruding portion and a second protruding portion. The first protruding portion protrudes from a side of the back housing. The second protruding portion opposes to the first protruding portion and protrudes from another side of the back housing. The connecting element is disposed between the master control lever and the slave valve, whereby the slave valve is rotated by a linear motion of the master control lever.

What is claimed is: 
     
         1 . A pneumatic tool, comprising:
 a main body, comprising:
 a front housing comprising a first accommodating space; and 
 a back housing connected with the front housing; 
   a power mechanism disposed in the first accommodating space;   a slave valve coaxially connected with the power mechanism;   a master control lever disposed at the back housing, the master control lever comprising:
 a first protruding portion protruding from a side of the back housing; and 
 a second protruding portion opposing to the first protruding portion, wherein the second protruding portion protrudes from another side of the back housing; and 
 a connecting element disposed between the master control lever and the slave valve, whereby the slave valve is rotated by a linear motion of the master control lever. 
   
     
     
         2 . The pneumatic tool of  claim 1 , wherein the back housing comprises a second accommodating space, and the slave valve is disposed in the second accommodating space. 
     
     
         3 . The pneumatic tool of  claim 1 , further comprising:
 a handle portion connected with the back housing, wherein the handle portion is U-shaped and extends along an extending direction of the main body, and the front housing, the back housing and the handle portion are substantially coaxial.   
     
     
         4 . The pneumatic tool of  claim 1 , further comprising:
 a handle portion connected with the front housing, wherein the handle portion is substantially perpendicular to an extending direction of the main body.   
     
     
         5 . The pneumatic tool of  claim 1 , wherein the connecting element is integrated with the master control lever or the slave valve. 
     
     
         6 . The pneumatic tool of  claim 5 , wherein the connecting element is integrated with the master control lever, the connecting element comprises a first tooth portion, the lave valve comprises a second tooth portion, and the first tooth portion engages with the second tooth portion. 
     
     
         7 . The pneumatic tool of  claim 5 , wherein the connecting element is integrated with the slave valve, the connecting element comprises a first tooth portion, the master control lever further comprises a third tooth portion, and the third tooth portion engages with the first tooth portion. 
     
     
         8 . A pneumatic tool, comprising:
 a main body, comprising:
 a front housing comprising a first accommodating space: and 
 a back housing connected with the front housing, wherein the back housing comprises a second accommodating space; 
   a power mechanism disposed in the first accommodating space:   a slave valve disposed in the second accommodating space, wherein the slave valve is coaxially connected with the power mechanism, and the slave valve comprises a second tooth portion; and   a master control lever disposed at the back housing, the master control lever comprising:
 a first protruding portion protruding from a side of the back housing; 
 a second protruding portion opposing to the first protruding portion, wherein the second protruding portion protrudes from another side of the back housing, and 
 a third tooth portion for directly engaging with the second tooth portion of the slave valve, whereby the slave valve is rotated by a linear motion of the master control lever. 
   
     
     
         9 . The pneumatic tool of  claim 8 , further comprising:
 a handle portion connected with the back housing, wherein the handle portion extends along an extending direction of the main body.   
     
     
         10 . The pneumatic tool of  claim 8 , wherein the master control lever is straight or substantially straight. 
     
     
         11 . The pneumatic tool of  claim 8 , further comprising:
 a handle portion connected with the back housing, wherein the handle portion is U-shaped and extends along an extending direction of the main body, and the front housing, the back housing and the handle portion are substantially coaxial.   
     
     
         12 . The pneumatic tool of  claim 8 , further comprising:
 a handle portion connected with the front housing, wherein the handle portion is substantially perpendicular to an extending direction of the main body.
